I have this--have 2 actually. I thought it was going to be the greatest ever and I wouldn't have to spend so much (and toss so much) on the refills for the "regular" tape roller. I found it only okay though--I'm pretty sure I followed the directions pretty closely but it didn't pick up as well. I found rinsing it off unpleasant--rinse it, clean the hair from the sink, blot it dry, ick. I kept them but I don't use them nearly as often as the tape and don't find them as good.

Pros: doesn't run out

Cons: not as good as tape

I thought this worked ok for my long haired cat, but not as well for my short haired Calico. Since we have four cats, we had to clean it often for it to be effective.

Pros: good for my long hair cats

Cons: not good for short haired cats

This is O.K. on the longer cat hair. On the short coarse types it doesnt work as well.

Pros: handy

Cons: none

This is a great product for a one time use, but then you have to rinse with water. Nice that it doesn't need refils.

Pros: works well at first

Cons: needs water to dehair

I don't like these very much. They don't work as well as tape. And it doesn't pick up the little fuzzies either.
I usually use some scotch tame, or a sticky roller because they work better.

Pros: Don't need to buy extra tape

Cons: don't work well
